About the Role This is an AI-native product engineering role with heavy agent ownership. You'll be building and shipping agent products directly — designing self-learning agent capabilities, iterating based on customer behavior feedback, and owning features end to end from zero to one. This is not a pure research role, a backend platform role, or generic full-stack work. The expectation is majority agent-building with strong product craftsmanship. What You'll Own

• Build high-quality AI agent products with genuine product taste
• Design and ship self-learning agent capabilities
• Own 0-to-1 product features from conception through deployment
• Develop agent infrastructure and behavior improvement systems
• Iterate on product based on customer behavior feedback
• Contribute to UX and product craft where needed
• Full-stack engineering as required to ship

Requirements

• 3–7 years of engineering experience
• Prior agent building and agent design ownership
• Comfort with 0-to-1 product ownership and ambiguity
• Frontend/design engineering background with strong product taste, OR AI engineering background with meaningful agent-building depth
• Baseline full-stack engineering capability
• Ability to work onsite in San Francisco 5 days/week

Nice to Have

• TypeScript fluency
• Agent observability or evaluation framework experience
• Behavior monitoring product experience
• Series A / seed startup experience
• Consumer-grade design sensibility

This Role Is NOT For

• Candidates with no prior agent building experience
• Pure backend or infrastructure-only engineers without product instincts
• Candidates who cannot commit to onsite in San Francisco
• Those who require heavily structured task management

Interview Process

• Initial approval review
• Founder vibe check
• Technical interview and role-specific interview
• Work trial
• Offer

Logistics
